To all whom it may concern:V

Beit known that I, IRA` J. OMALLEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new vand useful Improvements in Motor-Fans, of which the following is a speciication,

This invention relates to motor fans and aims to produce a fan adapted to be used for cleaning purposes, which 1s efficient 1n operation and cheap to manufacture.

Pneumatic Vcleaners of small sizes which have gone into general use, are operated either manually or by an electric motor.

It is the purpose of my invention to provid'e an automatically operated cleaner which can be attached to any convenient, waterfaucet, thus rendering possible, the use of cleaners of this character in dwellings or oees not supplied with electric power.

Another object of my invention is to sanitarily dispose of the dirt and dust with' which the air is laden, when it is drawn into the cleaner. In order lto accomplish this re sult, the discharge from the fancommuni- Cates with the interior of the motor casing so that the 'dust-laden air discharged from the fan casing into theinotor casing, is thoroughly mixed with the motor fluid thereby taken up by the water which is discharged connection.

Still another object of my invention'is to increase the efficiency of devices of this character by assisting the action of the fan blower. I accomplish this result by restricting the opening of the discharge pipe from the fan into the motor chamber, and position the supply nozzle for the motor within this restricted opening. By this construction the inflowing water draws the air through the discharge pipe from the fan casing by an injector action, thereby relieving the .compression of the air dischargedV from the fan, which, in ordinary constructions, tends to decrease the eiciency of the fan action.

A further object of vmy invention is the provision of means whereby discharge from the fan may be diverted so that the air-curbe used for 'blowing purposes, the means employed being a i, doublefseatin'g bereadily manipulated to claims.

convert the' cleaner into a blower when desired.

My vinvention will be best understood by reference to the following description when taken in connection with the accompanying drawings illustrating a preferred embodiment thereof, While its scope will be more particularly pointed out in the appended Referring to the drawings, Figure 1 isa sectional elevation on the line 1-1 of Fig. 2. Fig.2 is a section on theline 2--2 of Fig. 1. Fig. 3 is a section on the line 3--3 of Fig. 1. Fig. 4 is a section on the line 4-4 of Fig, 1, and, Fig. 5 is a perspective of my invention attached to an ordinary spigot.

In the drawings, reference character 6 designates generally, the casing, which is preferably made in three sections designated by characters 7, 8, and 9, respectively. The larger section 7 is substantially circular in cross-section as is shown in Fig. 2, and is provided with a laterally projecting hollow stud 10, which provides a bearing for the outer end of the motor and fan shaft 11, supported alsoin the bearing portion 12 provided on the inner wall of the section 8, as shown in A fluid motor wheel 13, of any pre Jferred construction, but which I have shown for the purpose of illustration merely, as a wheel comprising the usual curved blades 14,

' is rigldly secured upon the shaft 11 within the motor chamber 15.V Upon the inner end of the shaft 11 and within the fan chamber 16, there is xedly secured the fan 17, which may also be of any rapproved type, a common construction being shown on the drawings as comprising a number of reversely curved blades, best illustrated in Fig. 3. The section 9 of the casing comprises merely a plate adapted to cover the end of the fan and provided with an outwardly extending nipple 18 threaded to receive a coupling nut 19 carried by the member 20. The ordinary suction hose 21 provided with a cleaner 22 of. any preferred type, is attached to the member 20, and when the coupling-nut 19 is 'screwed onto the nipple 18, as shown in Figs. 1 and 5, the usual suction action through the cleaner 22, will be produced upon rotation of the fan., Y

' Water 0r other operating fluid is sup-l nio plied to the motor wheel 13 through a noz- 55 ordrain-pipe, whereby the impurities in the zle 23, which projects into 'the motor chamber throu h a restricted passage 24 disposed tangentia y to the motor, as shown 1n Fig. 2. The nozzle is held in position in the neck 25 of the section 7, by a flanged-mpple 26 which is threaded into the u per end of the neck 25 and bears agalnst t e upper flanged end 27 of the nozzle. The flangednipple carries a coupling-nut 28 of the usual form and size, adapted to be screwed upon the ordinary spigotor faucet 29.

The restrlcted opening 24 around the nozzle 23, constitutes the discharge outletl into the motor chamber from the fan chamber. As shown in Fig. 3, the discharge opening from the fan chamber is located near the top of the casing and communicates with the chamber 30 above the restricted opening 24 through a valve seat 32 which is screwed into a threaded opening in the inner Wall of the fan section 8, as shown in Fig. 4. It will be evident that when water is admitted' to the motor casing through the nozzle 23, that air will be drawn through -the restricted opening -24 around the nozzle by an injector action. and this action materially increases the eiiiclency of the fan by relieving :the compression in the disi charge passage from the fan, which would tend to react upon the fan blades and retard their action.

'In order to dispose of the dirt and dust with which the air drawn into the fan,

laden, I propose to cleanse the air and remove the dirt therefromby thoroughly mixing the air with the water in fthe motor chamber. In order to assist in this intermingling of the water and-air, the nozzle 23 is provided with a plurality of-spirallydisposed ribs 31, which im art a whirling motion to the air as it is suc 'ed through' the restricted passage 24 into the motor chamber. This whirling-motionof the incoming air assists in agitating the airin the mot-or chamber and also aids in disseminating the air through Athe spray occasioned by the impact of the water upon the motor blades,l so that before the. air escapes from the motor chamber through the discharge passage 32, it has been thoroughly cleansed of its impui-ities by the water. The water containing the sediment which it has accumulated from the air. may be discharged into a. sink, as shown in' Fig. 5, or the discharge passage 32-n1ay be connected direct with the sewer air are disposed of in asanitary and satisfactory manner without necessitating the subsequent removal from the cleaner of a bag of filth.. as is necessary with the ordinary type of'machine.

'It is often desirable to convert the cleaner into a blower for the purpose of blowing dirt out of otherwise-inaccessible places,or for lremoving dirt from delicate articles impossible to be cleaned with a brush. or the' the fan chamber passes through the Valve seat 32 into the chamber 30 vand into the motor chamber where it is discharged through the outlet passage 32 in the bottom thereof, as previously described. lVhen, however, it is desired to convert the mechanism into a blower` the valve 33 is turned against the seat 31 by means of the handlewheel 38, thus closing the port between the fan chamber and the motor chamber and oliening the portin the partition37. A pipe 39 is threaded'into a lateral boss 4() on the extension 36, said pipe being threaded at its outer end for the reception of the coupling nut 19 which can be readily uuserewed from the nipple 1S and attached to the pipe 3..

Assuming the valve to be seated against the seat 32, the discharge from the i'an will be conducted through the extension 36. the

pipe 39, and into the flexible hose 2l which may be supplied with any form of nozzle, and the mechanism may then be used for any purpose 'for which i-t is found conv-en.- ient to use a blow-er. The valve also serves as a controlling device by' means of which the speed of the fan may be regulated between certain limits. seated against Vthe seat 37 the ejector action of the motor fluid supply ydraws the air from the fan casing, thus relieving the back pressure in the casing and .reducing the atmospheric resistance .to thel rotation of the fan. thereby increasing the speedof the fan without varyingthe fluid supply to the motor. over the speed at which itv would run with the valve covering the port 32 and shutting loil? the eductive action .of theWater supply. I

It will be evident. that my device is light,

simple in construction and cheap to manufact-ure, that it may be readily attached to and detached from an ordinary water-faucet, and that it can be readily converted from a vacuum cleaner into a blower b v simply reversing the position of the controlling valve nd changing the attachment of the {iexible ose.

Various minor mechanical variations in` structure.' may be resorted to without departing from vthe spirit of my invention or sacrificing any of the material advantages thereof, therefore, I do not-wish to be restricted to the exact construction shown, but
